The RGBW version does not seem to exist yet "in the wild." I can't imagine the the analysis of RGBW would be a lot different from the analysis of RGBG, except a change in one filter in the color kernel.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-89498009336114752802012-01-28T07:03:31.103+02:002012-01-28T07:03:31.103+02:00Sony has an RGBW sensor.

There have been opinions expressed that while an RGBW sensor may reduce luminance noise, it actually will increase chrominance noise, which is far more objectionable and difficult to deal with than luminance noise. Also, the W sensor is likely to clip faster than the RGB sensors and may actually decrease dynamic range in high-contrast situations. While this matters for most people who are serious about photography the average cell phone snapper probably does not give a rats a** about highlight clipping or shadow chrominance noise.GroovyGeekhttps://www.blogger.com/profile/02461907290773954635noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-91174336136862936082012-01-28T05:14:28.456+02:002012-01-28T05:14:28.456+02:00Is this really a reverse engineering without a rea...Is this really a reverse engineering without a real device from chipworks?

Sony and Samsung have product announcements for RGB+W and OmniVision discussed an RGBClear CFA for sub-micron pixels (OmniBSI3) in its 2011 IISW paper. We’ll see what we find in our product teardowns!<br /><br />RF ChipworksAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-89511904450532133062012-01-27T20:12:48.284+02:002012-01-27T20:12:48.284+02:00Are there any (and which) camera modules out there...Are there any (and which) camera modules out there with RGBW?

The phones procured for our current analysis use a S5K3L1YX03 CIS with a Bayer patterned RGB CFA, and not a RGB+W CFA which appears to be an option for this device. Regardless of the CFA arrangement, it is still a very innovative device and Samsung’s achievement of being 2nd to market at the 1.1 µm pixel generation with a very thin 12 Mp module is good news for the company.<br />RF ChipworksAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-53359499167530997742012-01-27T12:01:09.902+02:002012-01-27T12:01:09.902+02:00wow..looks like everyone is going RGBW now...wow..looks like everyone is going RGBW now...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-54392330790862471232012-01-27T03:04:22.832+02:002012-01-27T03:04:22.832+02:00good catch!good catch!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-34077781366718823242012-01-27T02:47:12.812+02:002012-01-27T02:47:12.812+02:00Now who wouldn't want a free logic chip!Now who wouldn't want a free logic chip!Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.com
